法を用いた装置に急速に変わりつつある。2. Description of the Related Art In recent years, a color image forming apparatus using an electrophotographic process has been changed from an apparatus using an analog color image forming method based on a conventional analog copying machine to a material and a material of each element constituting the image forming process. Apparatuses using digital color image forming methods, which digitally process color data of each color in response to process characteristics and enable various image editing, are rapidly changing.

が出力出来るようになっている。[0003] Digital full-color images can be output on various types of recording media, which are characteristic of the electrophotographic process, such as thick and thin plain paper, second base paper, and OHP sheets.
【0004】しかし、各種の記録媒体へのカラー画像出

が対応を変化させているといったところである。However, in these conventional or proposed methods, the latent image formed on the photoreceptor is the same regardless of the type of recording medium, and the subsequent development and transfer -It is said that many of them are changing their response in fixing, especially in fixing.

よってなされているのが実情である。[0008] original imaging techniques, especially and image forming is performed under the balance of the whole process in the electrophotographic process technology, the optimization of the balance that is, each process unit is a standard plain paper 64 g / m 2 paper In fact, the other recording medium is set based on the uniform change of each portion of the image forming section under the set conditions, for example, the change of the fixing speed.

品質の均一安定化に対しては問題ののこるものである。In particular, OHP sheets and thick paper are fixed and output at a fixing speed that is half of the normal process speed. However, in the case of OHP sheets and thick paper, the image is viewed as a transmission image and a reflection image. They are completely different, and forming them under the same image forming process conditions is insufficient in image quality. Also, although the fixing speed is different between plain paper and OHP sheet, there is no difference in the developed image formed on the photoreceptor. The quality will be different.
In addition, since the response by the bias change of each part described above has a large relation with the surrounding environment and changes uniformly regardless of the content of the image, it is necessary to stabilize the image quality uniformly for various recording media. Is a problem.
